TURN THE POWER OFF TO THE MACHINE and test element leads
for continuity to ground and for resistance across the leads.
●
If all of these tests are ok, the relay has failed OFF
Display is Blank, No
LEDS are lit
●
If the red power switch is in the ON position and is NOT lit, there is lack
of power to the machine. Check your circuit breaker. Check the wall plug
if applicable.
●
If the red power switch is in the ON position and is lit, check that the lid
of the electronics box is tightly secured to the box. There is pressure
switch on the right side of the box which interrupts power to the electron-
ics when the lid of the electronics box is loose or removed.
●
On machines built prior to 01-01-2011, If the power switch is lit, the
safety switch is properly engaged, and the display is still dark. Either the
low voltage transformer has failed (see voltage output table below), or the
wires from the transformer to the display have been disconnected.
●
On machines built prior to 01-01-2011, Proper transformer voltages (to
ground):
Blue: 110v
Red: 110v
Grey: 12-15v
Black: 12-15v
The green wire is connected to ground and should have no voltage po-
tential

Test with an ohm meter across the element posts:
Voltage Wattage Ohms
110v 700 15
to
19
110v 1000 11
to
13
220v 700 64
to
72
220v
2000
46 to 52 each loop
220v
4000
23 to 26 each loop
220v
5000
18 to 22 each loop
●
Test the element post to the element body and you should not get a
reading of any kind. If you get even a quick flash reading, remove ele-
ment and inspect.
Leaks Hot
Water
Tap
●
If the drip is cold water, the water control valve on the cold side of the
mix valve is leaking. Open and clean the cold water valve.
●
If the drip is warm or hot water, the water control valve on the hot side
of the mix valve is leaking. Open and clean the hot water valve.
Steam Wand
●
A small amount of water will naturally accumulate in the steam wand
between uses if it is allowed to cool. This is normal for any machine.
Make a habit of purging the steam wand of all accumulated liquids before
and directly after steaming a pitcher of milk.
●
If the steam wand constantly drips warm water and is warm to the touch
even after an extended time without use, the valve will require a new
seal. Obtain and install a steam valve rebuild kit from your dealer, service
representative, or the Synesso™ factory.
